HOMOG-ENIZER.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed March 31, 1919. Serial No. 286,472.

To all whom it may concern:

Be it known that I, CHARLES S. ALLEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in I-Iomogenizers, of which the following is a specification.

My object is to make a homogenizer for internal combustion engines, and my invention consists of the novel features herein shown, described and claimed.

Figure 1 is a side elevation of an internal combustion engine provided with a homogenizer in accordance with the'principles of my invention, parts being shown in section to illustrate the homogenizer.

Fig. 2 is an enlarged fragmentary diametrical sectional detail showing the homogenizer in position in the intake manifold.

Fig. 3 is an enlarged perspective of the homogenizer.

Referring to the drawing in detail, the

- homogenizer consists of a flange plate 1 having a central opening 2, a row of distributer openings 3 concentric to the central opening 2, and bolt holes 4 and 5; and a conical mixer 6 extendin from the plate 1 around the opening 2 inside of the row of openin s 3 and having a series of horizontal slots It is intended that the combined area of the series of slots 7 shall be equal to the combined area of the row of holes 3.

In actual practice it is thought that the flow of fuel mixture through the manifold pipe leading from the carbureter has a' much greater velocity at its center than at the outer portion which is in contact with or near to the surface of the pipe, and that when considered in cross section the greater portion of the gasolene is carried at the center of the stream, and the problem is to make a complete circulation and mixture so that the gasolene will be thoroughly broken up and thoroughly mixed with the entire cross sectional area of air.

In considering this matter I have assumed that one-half of the cross sectional area of the stream of fuel mixture is overloaded with gasolene and that the other half is deficient, and that the overloaded portion radiates around the center and the deficient portion radiates around the overloaded portion, so I have arrangedthe conical portion of the homogenizer to be at the center of the passage and the flat portion to be around the conical portion, so that the overloaded stream will pass through the horizontal slots and shoot outwardly practically at right angles to the deficient stream which passes through the vertical openings. Of course, the relative proportions may be varied.

Preferably the slots are elongated horizontally and staggered vertically so as to form thin sheets of the overloaded mixture discharging outwardly across the line of travel of the streams of deficient mixture.

The homogenizer is applied by removing the bolts 8 from the flanges 9 and 10, placing the conical mixer 6 upwardly in the lower end of the manifold pipe 11 with the plate 1 fitting against the lower end of the pipe, and placing the carbureter 12 upwardly against the plate 1, and reinserting the bolts 8 through the flanges 9 and 10, and through the holes 1 and 5.

In the practical operation the explosive mixture produced by the carbureter 13 will pass upwardly throughthe row of openings 3, and through the opening 2, and through the slots 7 The streams passing through the openings 3 will collide with the streams passing through the slots 7 and the result will be a thorough mixing of the explosive mixture.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. A homogenizer comprising a flange plate having bolt holes and a central opening and a row of holes around the central opening; and a conical mixer extending from the flange plate around the central opening inside of the row of holes and having horizontal slots.

2. A homogenizer comprising a flange plate having a central opening and a row of holes around the central opening; and a conical mixer extending from the flange plate around the central opening inside of the row of holes and having horizontally elongated slots staggered vertically; so that the overloaded mixture passing upwardly through the central opening will pass out-- wardly through the slots in thin sheets crosswise of the streams of deficient mixture passing upwardly through the row of holes.

In testimony whereof I have signed my name to this specification.
